In the prior art, the traditional straightening equipment is mainly designed for linear workpieces (such as shafts and plates), and has the following defects for straightening of ring-shaped workpieces:

[0003] Poor adaptability: large-diameter seamless rings, usually 2-5 meters in diameter, are prone to radial oval deformation or circumferential local depression due to their own weight, and the traditional equipment cannot achieve synchronous straightening of the ring at multiple positions in the circumferential direction;

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0028] Please refer to Figures 1-7 The present application provides a technical solution: a straightening device for seamless ring production of a wind turbine, comprising a chassis 1, a base 2 welded on the top of the chassis 1, and serving as the bearing base of the entire device, the bottom of the base 2 is fixedly connected with the frame of the chassis 1 through expansion bolts, the top of the base 2 is slidingly connected with a limiting assembly, and the limiting assembly is used for fixing and transferring the ring.

[0029] The limiting assembly comprises double track sliding rails 3 fixedly installed on the top of the base 2, the double track sliding rails 3 are two parallel linear sliding rails, can bear the radial load and lateral impact of the ring and the base 4, the base 4 is slidingly connected with the double track sliding rails 3, limit blocks 5 are fixedly installed on the base 4, the limit blocks 5 are concave blocks, the opening width of the concave region is 2-3 mm larger than the radial thickness of the ring, support rods 6 are arranged in the concave region, first motors 7 are fixedly installed on the side wall surfaces of the limit blocks 5 at both ends of the support rods 6, the output ends of the first motors 7 are fixedly connected with the support rods 6, and the support rods 6 are used for installing the ring.

[0030] Work flow:

[0031] After the straightening system is started, first of all, the servo driver controls the sliding block driving base 4 of the double-rail slide rail 3 to move uniformly in the slide rail direction, the base 4 drives the limiting block 5 to move synchronously, so that the ring on the supporting rod 6 moves directly below the straightening detection execution mechanism, which can be a camera assembly; after the radial position of the ring is aligned, the straightening system switches the control logic, drives the first motor 7 to rotate at a set speed, the motor output shaft drives the supporting rod 6 to rotate around its own axis through the shaft coupling, and then drives the ring to rotate synchronously. Through the coordinated control of X-axis linear movement and Y-axis rotation, the ring can realize accurate positioning at any position in the circumferential direction during the straightening process.

[0032] The high-rigidity structure of the double-rail slide rail 3 and the closed-loop control of the servo first motor 7 ensure that the ring does not deviate or jam during the X-axis linear movement and Y-axis rotation, so that the straightening detection execution mechanism can accurately detect the deformation area of the ring, such as the major axis of the ellipse or the local concave part, avoiding the positioning error caused by traditional single-rail sliding or manual rotation, and significantly improving the straightening uniformity of the ring roundness and flatness.

[0033] The straightening detection execution mechanism is slidingly connected to the double-rail slide rail 3, and the straightening detection execution mechanism includes a side frame 8, both sides of the side frame 8 are provided for the movement of the ring, a camera assembly 9 is arranged on the top of the side frame 8, and the camera angle of the camera assembly 9 is aligned directly below;

[0034] The side frame 8 includes a bottom frame 10, the bottom frame 10 is slidingly connected to the double-rail slide rail 3, a single-rail slide rail 11 is arranged on the top of the bottom frame 10, a top frame 12 is slidingly connected to the single-rail slide rail 11, a driving member 13 is fixedly installed on the side wall surface of the top frame 12, the straightening system drives the driving member 13 to move, drives the bottom frame 10 to move along the double-rail slide rail 3, and then drives the entire side frame 8 to move, the straightening system drives the top frame 12 to move along the single-rail slide rail 11, and then drives the entire top frame 12 to adjust longitudinally, so as to adapt to the movement of the ring;

[0035] The top middle region of the base 2 is provided with a fixing assembly located between the double-track slide rails 3, which comprises a fixing block 14 fixedly installed on the top middle region of the base 2, an electric control rod 15 provided at one end of the top of the fixing block 14, a second electric motor 27 fixedly installed at the middle region of the electric control rod 15, a first telescopic rod 17 fixedly installed at the output end of the second electric motor 27, and a lifting plate 16 fixedly connected with the end of the first telescopic rod 17 through bolts, wherein the lifting plate 16 is a rectangular steel plate with a blackened surface for corrosion protection, and is divided into two surfaces with independent functions, one of which is provided with a groove 18, and a plurality of groups of electric control balls 19 are arranged in the groove 18, and the electric control balls 19 are remotely controlled to start and stop through a straightening system, so as to realize the fixing and boosting of the ring piece; and the other surface is provided with pressure sensors 20 arranged densely, and the lifting plate 16 with the pressure sensors 20 is arranged in close contact with the outer surface of the ring piece before the straightening process of the ring piece is remotely controlled by the straightening system.

[0036] Pre-positioning before detection: when the ring piece moves to the position directly above the fixing assembly with the limiting assembly, the straightening system drives the electric control rod 15 to extend, and the lifting plate 16 is lifted to a position 50 mm below the lower surface of the ring piece; the first telescopic rod 17 is synchronously extended, so that the pressure sensor 20 of the lifting plate 16 is in close contact with the outer surface of the ring piece, and the pressure distribution data of the initial deformation of the ring piece is collected through the pressure sensor 20, such as the local pressure concentration area corresponding to the concave part of the ring piece, which is used in cooperation with the limiting assembly.

[0037] Auxiliary fixing during the straightening process: after the detection of the pressure sensor 20 is completed, the first telescopic rod 17 is retracted, the second electric motor 27 is driven to rotate passively, the lifting plate 16 is switched to the groove 18 facing upward, the electric control rod 15 is continuously lifted, the electric control balls 19 are in contact with the lower surface of the ring piece, the straightening system controls the electric control balls 19 to start, and the electric control balls 19 provide rolling support when the ring piece rotates, so as to reduce the friction resistance and the load of the first electric motor 7; when the ring piece needs to be fixed, such as the pressing and straightening stage of the pressure head, the electric control balls 19 are powered off and locked to become rigid support to prevent the displacement of the ring piece.

[0038] Double-axis linkage detection to improve the full-area coverage: the lateral frame 8 is moved along the horizontal direction of the double-track slide rails 3, and the top frame 12 is adjusted along the vertical direction of the single-track slide rail 11, so that the camera assembly 9 can flexibly adjust the field of view range and cover any position of the ring piece in the circumferential direction. Compared with the traditional fixed-position detection device which can only detect the central region of the ring piece, this detection method is more flexible.

[0039] The rod body surface of the support rod 6 is provided with a plurality of straightening assemblies, the straightening assembly comprises a plurality of second telescopic rods 21 mounted on the surface of the support rod 6, the second telescopic rods 21 are all slidingly connected to a sliding sleeve arranged on the surface of the support rod 6, and each second telescopic rod 21 can independently operate; the end of each second telescopic rod 21 is fixedly installed with a third motor 22, the two ends of the third motor 22 are respectively electrically controlled bearing installed with a first roller 23 and a second roller 24, the first roller 23 and the second roller 24 are hard alloy rollers, a third telescopic rod 25 is fixedly installed at the top center of the third motor 22, and the end of the third telescopic rod 25 is fixedly installed with a third roller 26, the third roller 26 is a polyurethane roller;

[0040] The artificial or intelligent mechanical arm device moves the ring to the outside of the straightening assembly, and sleeves into the supporting rod 6. After the ring is moved to the outside of a straightening assembly, the straightening system drives the second telescopic rod 21 to move, and the third motor 22 moves, the third motor 22 moves to drive the first roller 23 and the second roller 24 to contact and press against the inner surface of the ring. At this time, the ring is fixed by the first roller 23 and the second roller 24 from the inside, and at this time, the first roller 23 and the second roller 24 are in non-moving contact with the inner wall of the ring. Then, it ensures that the fixing effect on the inner wall of the ring is better, and avoids the rotation of the ring after the fixing process is completed due to the factors of the first roller 23 and the second roller 24. In the above fixing process of the inner wall of the ring, the third roller 26 has no contact with the inner wall of the ring. The straightening system drives the first motor 7 to operate, and then drives the supporting rod 6 to rotate. The supporting rod 6 rotates to drive the straightening assembly to rotate. The straightening assembly rotates to drive the ring to rotate. The ring rotates to cooperate with the straightening detection execution mechanism to detect. If it is detected that there is a region that needs to be corrected on the outside of the ring, cooperate with the external straightening equipment to straighten the outside of the ring. The external straightening equipment can be a cutting device. The requirements of the outside and the inside of the ring are inconsistent. Therefore, the straightening process of the region that needs to be straightened on the outside and the inside of the ring is inconsistent. If it is detected that there is a region that needs to be straightened on the inside of the ring, the straightening system drives the third telescopic rod 25 to extend, and then drives the third roller 26 to move and press against the inner wall of the ring. The third roller 26 is internally provided with a storage cylinder, and an electrically controllable guide hole is arranged on the outer wall surface of the third roller 26. The third telescopic rod 25 is driven by the straightening system to operate to drive the third roller 26 to mark the inner wall of the ring. After the marking is completed, the third telescopic rod 25 is reset by the straightening system. Then, the straightening system reserves two second telescopic rods 21 to fix the inner wall of the ring. The remaining second telescopic rods 21 are retracted and reset. Then, the third motor 22 is driven to rotate 90 degrees to drive the first roller 23 and the second roller 24 to slide along the inner wall of the ring. Then, the two reserved second telescopic rods 21 are driven to match the first roller 23 and the second roller 24, and the remaining first roller 23 and the second roller 24 are retracted. The roller pressing process is carried out on the marked region of the inner wall of the ring, and then the inner wall of the ring is rolled and straightened.

[0041] The straightening system drives the first roller 23 and the second roller 24 to roll and press the marked region with a pressure of 100N. The rolling frequency is 3 times, and the rolling stroke is 20mm each time. The plastic deformation eliminates 0.2mm protrusions. The electrically controllable guide hole marking function of the third roller 26 and the independent control ability of the second telescopic rod 21 make it only need to apply local pressure to the marked region for the inner side straightening of the ring. Compared with the traditional full-week rolling efficiency, it is improved a lot. At the same time, the flexible contact of the polyurethane roller and the rigid rolling of the hard alloy roller cooperate to avoid surface damage during marking, and traditional metal marking is easy to leave scratches. It also ensures the plastic deformation effect of the rolling straightening.
